Frankie Grande is Ariana's brother, he's also known for his polarizing role on Big Brother.
Now, he's opening up about his relationship with two men who are already married to each other.
Together, the three of them are in a throuple -- and Frankie explains that he is the newest addition.
Frankie Grande is dating two men: Daniel Sinasohn and Mike Pophis.
Daniel Sinasohn is a human rights attorney who has also worked as a model.
Mike Pophis, who goes by Dr. Mike on Instagram, is a doctor of Internal Medicine.
Frankie, Mike, and Daniel have been posting photos together on social media for a while now.
Last weekend, as Bette Midler's Hulaween soiree in New York City, Frankie made it clear that they're in a relationship.
Speaking to Us Weekly at the event, Frankie made things official.
"These are my boyfriends," Frankie announced.
"[We’ve been dating for] almost three months," Frankie shared.
He then makes a joke about how transitory some same-sex relationships can be, saying: "but in the gay world, it’s like five years."
(That stereotype applies to men, while the opposite stereotype is projected onto women; both stereotypes are heavily debatable)
Frankie also shared a little TMI about his relationship -- but keep in mind, this was a Halloween party.
When Frankie was asked about the best part of dating Daniel, he replied bluntly: "his d--k."
Congratulations are in order, we suppose.
Daniel's legal career is something that he's tried to separate from his modeling, so we're not sure if he appreciated Frankie's bluntness.
To be fair, Frankie also gushed that Daniel is "very smart."
"So is Mike," Frankie added. "Mike is also very smart."
At Heidi Klum's annual Halloween party presented by Svedka Vodka and Party City, Frankie added more details.
This time, the details were safe-for-work.
"I’m the new addition," Frankie shared.
Mike and Daniel are married, so that makes sense.
When asked how their relationship works (such an awkward question for polyamorous folks), Frankie didn't go into specifics.
Frankie replied: "Let’s just say it does."
Frankie also issued a statement to Us Weekly.
"Mike and Daniel are both extraordinary people and I think the world of them," Frankie raved.
"Each of them complete me in different ways," he continued. "And I am honored to be in this very special, very fun relationship."
That is so sweet.
Though Frankie can be a polarizing figure (mostly among Big Brother viewers), he deserves credit for using his platform to speak openly about polyamory.
The more people discuss it, the sooner that it will gain wider acceptance.
That could really make life easier for the polyamorous community.
Polyamory is not for everyone -- but neither is monogamy. Neither are relationships at all, for that matter.
Some people fall in love with multiple people without falling out of love, and don't want to break up or cheat.
Others find that they can experience the benefits of romance with more cooperation and less emotional labor than they could with only one partner.
And then some folks are just living their best lives and taking it one day at a time.
We'd like to see more people feel comfortable and confident discussing their polyamorous relationships.
It's almost 2019.
